Subject: [PATCH v4 09/10] acpi/numa/hmat: Register HMAT at device_initcall level
Date: Mon, 24 Jun 2019 11:20:21 -0700
Message-ID: <156140042119.2951909.7727308817426477621.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <156140036490.2951909.1837804994781523185.stgit@dwillia2-desk3.amr.corp.intel.com>

In preparation for registering device-dax instances for accessing EFI
specific-purpose memory, arrange for the HMAT registration to occur
later in the init process. Critically HMAT initialization needs to occur
after e820__reserve_resources_late() which is the point at which the
iomem resource tree is populated with "Application Reserved"
(IORES_DESC_APPLICATION_RESERVED). e820__reserve_resources_late()
happens at subsys_initcall time.
